Horrible posts

I have read some threads on this forum and I have to say i have been shocked. Some people should not write on this forum, that is for sure. But instead of going on for pages, giving those people the satisfaction of our attention, maybe we should ignore them and give our help to people who really deserve it. I am 28 years old and am 22 weeks pregnant now. the first term of my pregnancy, i did not know what to do and it is a young mum to be who gave me some advice via PMs. She was in a difficult situation, had to chose between her family or boyfriend and she took the time to answer my questions and reassure me on a lot of things and all that at 16 years old. I also had a chat with very young parents who were extremely mature for their age.
Some teenagers(and adults) are totally immature and careless and there will always be people like this who cannot give a damn about other people including their own children because they want to drink, a social or sex life or whatever.
However, I would like to say I have seen some teenage mums who were much better than any other adult mums and those kind of posts are so unfair towards them.
So don't you think we should ignore the posts that we do not think are real and help others instead? no point in telling those people not to write on the forum because they will still do, so better being more clever than they are and just ignore them?
